[[Gambar:Sun_in_February_(black_version).jpg|thumb|right|[[Srengéngé]] yaiku sumber energi kanggo [[kauripan]] ing [[Bumi]]. Srengéngé ngasilake utamane [[energi termal]], [[energi panas]] lan [[energi radian|energi radian (cahya)]].]]
Ing [[fisika]], '''energi''' iku [[Properti fisika|properti]] saka obyek kang bisa [[Transfer energi|ditransfer]] kanggo obyek liyane utawa diowahi menyang macem-macem bentuk.<ref>{{Cite book|title = Thermal Physics|url = https://books.google.com/books?id=c0R79nyOoNMC|publisher = Macmillan|date = 1980-01-15|isbn = 9780716710882|language = en|first = Charles|last = Kittel|first2 = Herbert|last2 = Kroemer}}</ref> "Kemampuan saka sistem kanggo nindakake karya" iku gambaran kang umum, nanging ora bener amarga energi ora kudu kasedhiya kanggo karya.<ref>{{cite book|title=Biomechanics and Biology of Movement|author1=Benno Maurus Nigg |author2=Brian R. MacIntosh |author3=Joachim Mester |publisher=Human Kinetics|year=2000|isbn=9780736003315|page=12|url=https://books.google.com/books?id=1BG78utt6VUC&pg=PA12&dq=energy+%22capacity+to+perform+work%22#v=onepage&q=energy%20%22capacity%20to%20perform%20work%22&f=false}}</ref> Kayata, ing [[International System of Units|Unit SI]], energi diukur nganggo [[joule]], lan siji joule wis ditetepake "kanthi mekanik", kang energi ditransfer kanggo obyek kanthi [[karya mekanik]] saka obah kadohan saka 1 [[meter]] marang [[gaya]] 1 Newton.<ref group=note>Energi (lan satuané) kerepé didèfinisikaké nganggo [[Karya (fisika)|karya]] kang bisa dilakoni. Tapi, tèknisé iki mung kira-kira, amarga [[hukum térmodinamika kaping pindho]] artine karya kang bisa dilakoni sawijining system mesthi kurang saka energi total sistem, amarga [[panas buangan]].
